Functional Size Inspection
Functional gauging takes into account the cumulative effects of diameter, lead, taper, flank angle and form error. Experience the same functionality of ring and plugs with the added benefit of accurately inspecting a range of sizes.
Functional thread inspection gages, or GO/NO GO gages, measure thread diameters. These functional gages are adjustable within a size range and use interchangeable thread rolls to measure different pitch threads.
Setting dimensions for the functional pitch diameter gages are provided by the TDWIN Thread Disk software. Gages can be set with specifically sized rod standards or a MIC TRAC Gage Setting System (MT-3000).
External Functional Size
These functional size inspection (or “GO/NO GO”) gages measure external thread diameters ranging from ⅝” – 24″. The gages are adjustable within a size range and use interchangeable thread rolls to measure different pitch threads.
Setting dimensions for the functional pitch diameter gages are provided by the TDWIN Thread Disk Software. Indicators have a .5″ travel and .0005″ resolution with higher resolutions available.
Thread roll sets not included.The software and thread rolls are sold separately.
